Faster hard drives

These hard drives use a different kind of memory, and don't have moving parts. Moving parts in computers are the parts that are most likely to break. Companies like Amazon and Ebay pay 10,000 dollars for special hard drives that use RAM instead of spinning disks, so that everything runs faster.

Fusion io will charge $30 a gigabite, so a 100GB hard drive would be about 3000 dollars. They will make huge profit as long as there isn't competition (and there will be - hitachi for example). Hard drives are super important for databases - and making databases this much faster changes what is possible on internet. For example, Google has 100,000 computers working together so that everything appears fast to the user. With these hard drives, it makes it possible bring more interesting applications to larger groups of people.

While there is no substitute for a good algorithm, it's nice when technology simply gets better (for those who can afford it).
